CAR AND LOCOMOTIVE REPLACER.

SPECIFICATION formingpart of Letters Patent N0. 597,951, dated January25, 1898.

i Application filed May 22, 1897. Serial No. 637,740. (No modeL) To LZZwhom it may concern:

Beit known that I, GEORGE A. BULL, a citizen of the United States,residing at Marion, in the countyof Marion and State of Ohio, haveinvented certain new and useful Improvemen ts in Car and LocomotiveReplacers;

and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to car and locomotive replaoers.

The object is to provide a car-replacer which will be certain inoperation to replace a car or locomotive that has left the track Withoutinjury either to the rail or to the car-truck. Furthermore, to provide acar-replacer which will be adapted for use on either rail-that is tosay, in which it will not be necessary to remove the replacer from vonerail to the other, according as the car may be derailed from one or theother rail, but which may be used when the car-Wheels are on either sideof a rail simply by moving the replacer from one side of a rail totheother side of the same rail. Furthermore, to provide a car-replacerin which all jar or impact between the rail and the car Wheels when thewheels leave the replacer will be obviated, and, finally, to provide acar-replacer which will be simple of construction, eicient and durablein use, which will not be liable to get out of repair fromlong-continued use, and which may be constructed at a low figure. t

In a car-replacer characterized bymy invention I employ a skid or base,the same being approximately AWedge shape in plan and iu elevation. Thisskid-is by preference made hollonr on its under side for the purpose oflightness, and in order to strengthen and thereby to present a morestable structure it is reinforced by means of bridges cast integral withthe skid, rlhe upper surface of this skid is rounded from .toward itscenter out- Ward and downward on each side, in order to removeunnecessary strain Afrom the treadbar and also to cause the truck-Wheelsto take the track in an easy manner and Without jar. The tread-bar ispivoted at one end to the skid, preferably by means ofy a pin, the inneror under end of which is held in place from disengagement with the skidby means of an ordinary @otter-pin. This bar has a limited range ofmotion, the same being conn trolled by means of a slot in the skid,Which is engaged by a pin passing through the bar, so that when the barhas reached the limit of movement on either side of the skid it Willbeeffectively held in place against further lateral motion. Ii' desired,pins or stops may be employed for the purpose of locking the bar rigidlyin position at its limit of lateral adjustinent on either side, so thatWhen the skid is positioned adjacent to a rail the bar cannot move bythe strain applied to it by the truck-wheels. In order to adapt thetreadbar for' connection with rails of different heights, so as toobviate shoring or bolstering of the skid, as is customary', I providethe free end of the tread-bar with a pivoted knuckle joint, carrying aswinging hook adapted to engagewith the tread of the rail, this hook bypreference being semicircular in crosssection, so that when seated uponthe rail it will present a firm bearing and thereby remove danger ofstrain both from the hook and from the knuckle-joint, and at the sametime minimize jar to the truck-Wheels when the same leave this hook.

As before stated, this replacer is adapted to be used 0n either side ofthe same rail, and in order to eifect this result the tread-bar ispivoted centrally of the Width ofthe skid, so that by swinging it to itsextreme limit either to the right or the left it will be adapted tocause either the iiange of the Wheel to ride over the rail or the treadof the Wheel to take the rail gently and Without jar, or the iiange ofthe Wheel to ride upon and obliquely across the tread of the rail and toseat itself Without jar. By this arrangement the truck Will be caused toregain the rail with but slight, if any, jar and Without any lateralslide, such as would tend to strain the rail or break the flange of theWheel, whereby damage to the parts mentioned will be obviated.

Further and more speciiic details of construction will be hereinafterdescribed and.

claimed.

In the accompanying drawings, forming a part of this specilication, andin which like IOO ment of my invention, although it is to be understoodthat other forms of embodiment thereof may be employed without departingfrom the spirit of the same, and in these drawings Figure l is a view inperspective displaying a section of track with a truck derailedtherefrom, showing my improved replacer in one position for reseatingthe truck upon the rails. Fig. 2 i's a similar View showing the truck onthe rail on an opposite side of the track, showing also the positionoccupied by my improved replacer. tive View of the replacer.v Fig. 4 isa bottom plan View of the replacer, showing the peculiar construction ofthe under side of the skid.`

Fig. 5 is a longitudinal sectional View of the device. Fig. 6 is adetached detail View of the end of the tread-bar, showing the differentlateral adjust-ments which may be assumed by the hook on theknuckle-joint that engages the rail. Fig. 7 is a View in side elevationshowing the different vertical adjustments that may be assumed by thehook on the knuckle-joint that engages the rail; and Fig. 8 is atransverse sectional view taken on the line 8 8, Fig. 6, showing incross-section the shape of the rail engaging the hook on theknuckle-joint.

Referring to the drawings, A designates the skid, which, for purposes ofstrength, lightness, and durability, is constructed in this instance ofcast-steel, although any other suitable material combining thesequalities may be employed. The under side of the skid is cast hollow andis reinforced by transversely-disposed bridges or braces a, of whichthere may be any number, two being shown in this instance. In plan andin elevation the skid is approximately wedge shape, and from the tail orthin edge of the wedge the corners 4are rounded or beveled, as shown ata2, for a purpose which will presently appear.

B designates the tread-bar, which may be constructed of any suitablematerial, preferably of steel, and in longitudinal section preferablywedge shape, in order that the truck-wheels will be presented to agradual incline, so as to obviate unnecessary strain as the trucks arebeing moved over these bars. The rear end of this tread-bar is pivotedto the skid by means of a pin b, which, by preference, is cast integralwith the bar and extends through an opening a3 in the skid and is heldfrom accidental separation therefrom by means of an ordinary cotter orsplit pin b2, passing transversely through the pin b. The free end ofthe tread-bar carries a knucklejoint b3, which is pivotally connectedwith the tread -bar in this instance by an ordinary rule-joint, andsecured to this knuckle-joint is a hook b4, which is of a shape toengage the tread of a rail and thereby hold the bar from lateraldisplacement when the truck is being seated. The knuckle-joint is bypreference wedge shape in plan to present under all conditions a broadbearing-surface tothe rail. In order to limit the lateral movement orFig. 3 is a perspecrange of the tread-bar, the skid is provided With acurved slot a4, in which works apin b5, carried by the tread-bar, thewalls of the ex tremties of `this slot serving to lock the bar in placewhen it has been moved to its limit on each side. In addition to theslot a4 and pin b5 stop-pins t5-may be employed, which may be insertedin openings a6 in the skid. By means of the knuckle-joint b3 the hook b4lmay be adjusted to fit rails of different heights, and by means of apivotal connection between the hook and the knuckle-joint the h ook maybe moved, as shown in Fig. 6, to any angle to bring it into lockedrelation with a rail. i By this arrangement the skid may be moved to orfrom the rail, Vaccordin g as the truck-wheels are close to or removedfrom the rail, so that the truck may be seated with readiness and veaseunder all conditions. f As will be seen by reference to Fig. 8, the hookh4 is approximately semicircular in crosssection, as shown at be, sothat when seated upon a rail it will present a firm bearing and therebyremove danger of strain both from the hook and from `the knuckle-jointand at the same time minimize jar to the truck- ,Wheels when the sameleave this hook.

In order to prevent the skid from slipping, the saine is provided with aseries of pins or spurs a7, which are by preference cast integral withthe skid, although, if preferred,they may be detachably connectedtherewith, and these spurs will sink into the ties as soon as pressureis brought to bear upon-the skid and thereby hold the latter securely inplace.

In some instances, as where the ties are arranged at a distance apartgreaterk than the length of the skid, it will be desirable to providemeans whereby the skid will be prevented from sinking into the groundwhen pressure is brought to bear upon it and which would result from thehollow construction of the under side of the skid. In order to obviatethis, I may cast a bar or strip a8 the length of the skid or only aportion of the length thereof, as may be preferred. This will present abroad bearing-surface to contact with the ground, as will be readilyunderstood. y

The outer or enlarged end of the skid will be provided with a handhold0.9 in the nature of a half-link, by which the skid may be moved aboutwith readiness and ease.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is-
